The military officer laughed uproariously.
"Nothing like being candid," he remarked. "Did you have a good voyage?"
"Excellent. And what is more, we pa.s.sed within two hundred metres of a British battleship, and she never had the faintest notion that one of our most formidable _unterseebooten_ was anywhere in the Mediterranean."
"You bagged her, of course?"
"Unfortunately, no. There were too many English destroyers about, and we had not enough petrol to risk being driven miles out of our course.
There was sufficient only to bring us here, and here we have been the last three days with the English fleet within easy striking distance, yet we were helpless."
"You will not be for long," rejoined von Elbing, "so the sooner we get to work the better."
"Meanwhile, do me the honour of broaching a bottle of the best Rhine wine," said von Birmitz. "Our boat is but a small one for a man of your build, but with caution you will be safer than in Fort----"
"Nagara," added the other. "You are right. When those English sh.e.l.ls begin to fall it is a bit of a tight corner, but fortunately von Biltz and I have a snug and safe retreat."
The officers embarked in the canvas boat and were rowed off to the submarine. Before going below, von Birmitz spoke to a seaman, who instantly semaph.o.r.ed to a German sentry stationed on the high ground at the entrance to the inlet.
Crosthwaite had not noticed the fellow before. He now realized that he had run a great risk of detection, for, in his curiosity to overhear the conversation, he had approached so closely to the edge of the cliff as to be clearly visible from the place where the sentry from the submarine was posted.
The seaman semaph.o.r.ed a reply, which was evidently satisfactory, for, rubbing his hands gleefully, the Lieutenant-Commander followed his guests down the narrow hatchway.
A little later the submarine, the deck of which was previously only just awash, began to rise till she showed a freeboard of nearly six feet.
d.i.c.k estimated that she was about three hundred feet in length, and considerably longer than the latest type of British submersible. Her conning-tower was of an acute oval section and apparently s.p.a.cious.
There were two periscopes, while abaft the conning-tower was a light signalling-mast supporting the wireless aerials. Fore and aft were short quick-firing guns mounted on water-tight disappearing platforms, while, owing to freeboard she exposed, the Sub could see the ends of a couple of broadside torpedo-tubes, both within ten feet of the "midship section.
"She carries six tubes at least," whispered d.i.c.k; "two on each side abeam and two in the bows. It"s just likely she has a pair of stern tubes also. No wonder she wants a good supply of torpedoes; yet what has she done with those she brought with her? That fellow made no mention of having used any. h.e.l.lo, she"s getting under way."
As he spoke, men hurried up from below. The propeller began to churn and the submarine gathered way. Describing a semicircle she slowed down, while a couple of seamen in the Berthon boat began to run a line ash.o.r.e. To this was bent a stout hawser, which, as soon as it was made fast to the stump of a tree, was carried to a motor-capstan on deck.
Slowly and with extreme caution the _unterseeboot_ was warped close insh.o.r.e until it was possible for a man to leap from her deck on to dry ground.
It was the only place in the creek where deep water existed close to the sh.o.r.e, for elsewhere the depth shoaled gradually.
The work of replenishing the submarine"s stock of petrol proceeded with the utmost dispatch, each large steel drum being carried to the beach by Turks, whence it was whipped on board by means of a light steel crane. The drums were quickly emptied into the vessel"s tanks, and the empties taken ash.o.r.e again and reloaded on the wagons.
Nearly the whole morning was spent in taking on board the supply of petrol. According to d.i.c.k"s estimate, the quant.i.ty was sufficient for a surface run of at least four thousand miles.
After that part of the business was completed, the additional torpedoes were cautiously slung inboard and pa.s.sed down a long, narrow hatchway.
In this operation the Turkish troop took no part. The handling and stowage was performed entirely by the submarine"s crew.
In the midst of these operations the seaman sentry began signalling frantically. Summoned from below, von Birmitz hastily appeared, followed by his guest and the other officers of the submarine who were not engaged In superintending the work.
Somewhat ungracefully von Elbing leapt ash.o.r.e, landing on his hands and knees. He shouted an order to the men of the convoy, hurried up the path, and was soon lost to sight.
Meanwhile the crew of the submarine were hurriedly securing hatches, and lowering the disappearing guns and the wireless mast. In their haste they were unable to pa.s.s below four torpedoes lying on deck.
These they fastened to ring-bolts by means of stout ropes, then at the Lieutenant-Commander"s orders the crew cast off the hawsers and scurried-below.
Twenty seconds later the submarine sank in twelve fathoms of water, till from their elevated position the two British officers could just discern her outlines as she glided towards the centre of the creek.
"They"ve smelt a rat," declared d.i.c.k.
"One of our destroyers, by Jove!" added Farnworth, as a four-black-funnelled, black-hulled craft proudly displaying the white ensign could be seen beyond the barrier of rock that almost closed the narrow entrance.
"We must attract their attention, regardless of the consequences,"
declared d.i.c.k, and springing to his feet he waved the silk handkerchief that had previously rendered good service as an insulator to von Eitelheimer"s scabbard.
"Let"s fire our revolvers, sir," suggested the midshipman.
"Can but try," replied d.i.c.k recklessly. "Only I"m afraid they won"t hear; the wind"s the wrong way."
Both men emptied their revolvers In the air, but to their intense disappointment the destroyer held on her course without attempting to reply, and presently she was lost to sight behind the rising ground.
"Think that rotten submarine will have a go at her, sir?" asked Farnworth.
"Hardly likely. She"ll want to try her luck at bigger game," replied d.i.c.k. "But the point is this: we must do our level best to warn our people--and as soon as we possibly can. It will take the German submarine another five hours at least to prepare for sea, and those fellows won"t reappear in a hurry until the coast is perfectly clear.
The question is, did the troops belonging to the convoy hear our shots?
If so, we must look out for ourselves."
"What do you propose, sir?"
"Wait till the submarine resumes loading up, then we"ll cut back and see if we can"t collar a couple of horses. You"ll remember the Turks left their horses hobbled, and there was no one left on guard. Then we"ll go all out and make for k.u.m Kale. If we find the French there, well and good; if not, we must make a raft or sneak a boat, and trust to luck to be picked up by one of our patrol ships."
Cautiously the two fugitives made their way backward along the terrace running parallel to and above the mountain path. After traversing nearly a quarter of a mile they halted abruptly, for seated on a rock by the side of the ridge were two German military officers, who, to pa.s.s away the tedious wait, had climbed the hillside and were now enjoying cigars.
"Luckily, we were not making a dash for it," remarked d.i.c.k. "But at the same time we did right to make a reconnaissance by daylight. I"m afraid these terraces terminate abruptly, but we"ll see."
Accordingly Crosthwaite and his companion climbed to the next ridge.
Still not satisfied they ascended to the next, which was about two hundred feet above the one where the two German officers had unwittingly cut off their retreat.
"There"s only the road for us," announced d.i.c.k after a while. "See, all these terraces end abruptly. There"s a precipitous gorge right through the mountain."
"A good thing we didn"t try it in the dark, sir," said the midshipman.
"A fellow wouldn"t be worth much if he pitched over there."
"Well, let"s get back to our former hiding-place," suggested the Sub.
"It"s about time the submarine appeared."
d.i.c.k was right in his surmise, for the boat had just emerged from its hiding-place and was being warped in towards the sh.o.r.e.
"Where"s von Elbing and his men?" demanded the Lieutenant-Commander of his subordinate. "One would think that the English destroyer was searching for him!"
"He"s coming," announced the German sub-lieutenant.
"About time," grumbled von Birmitz. "It will be quite another twenty-four hours before they go to Chanak and back, and we can"t move until they do."
The interrupted work was continued, while the German officers chatted on the beach. Presently the seaman stationed on the cliffs as a look-out began signalling, his message being taken down by another seaman on the deck of the submarine.
"Gott in Himmel, what is this?" exclaimed von Birmitz dumbfoundedly, when the message was handed him. "Von Elbing, listen. Our man reports that as soon as we were submerged two German officers began signalling to that cursed English destroyer, and that they even fired shots to attract her attention."
